뇌파는 뇌신경 세포의 활동으로 발생하는 전기적 변화를 두피 표면에서 측정하여 기록한 것이다. 뇌활동의 변화는 공간적 시각적으로 파악할 수 있는 지표이며, 바이오 센싱을 통해 측정된 데이터를 활용한 미디어 컨텐츠 적용이 최근 시도되고 있다. 본 연구는 미디어 컨텐츠 평가를 위한 감성 지표로 뇌파 데이터를 인간의 오감으로 느낄 수 있는 표현으로 변환하는 프로세스를 구현하는 함으로써 현재 행해지고 있는 많은 미디어 아트에 대해 뇌파를 활용한 실시간 객관적 감성지표를 완성하는데 목적이 있다. 이에 대한 사전 연구로 본 논문에서는 측정된 뇌파 데이터를 인터렉티브 컨테츠적인 요소인 사운드로 청각화 하는 과정을 구현하였다.

As a passive soundscape facility, fountain is a useful way to give place such as public square, park identity and vitality. In this study, to know the optimistic distance and sound level range from fountain, sound levels due to distance were measured and subject responses were checked by questionnaire. Levels from 56dB to 68dB are recommended by subjects and moving forward to fountain decreases less comfort ratio than backward Moving forward 5m and backward 5m(total range 10m), there is little difference in comfort ratio. The results of this study could used for street furniture location design and P.A system output level.

The final aim of the present study is to build a system of converting a color image into musical elements based on a synesthetic perception, emulating human synesthetic skills, which make it possible to associate a color image with a specific sound. This can be done on the basis of the similarities between physical frequency information of both light and sound. As a first step, an input true color image is converted into hue, saturation, and intensity domains based on a color model conversion theory. In the next step, musical elements including note, octave, loudness, and duration are extracted from each domain of the HSI color model. A fundamental frequency (F0) is then extracted from both hue and intensity histograms. The loudness and duration are extracted from both intensity and saturation histograms, respectively. In experiments, the proposed system on the conversion of a color image into musical elements was implemented using standard C and Microsoft Visual C++(ver. 6.0). Through the proposed system, the extracted musical elements were synthesized to finally generate a sound source in a WAV file format. The simulation results revealed that the musical elements, which were extracted from an input RGB color image, reflected in its output sound signals.

This work defines user intention according to intention range, and also proposes an interactive sound installation which reflects and varies above features. User intention consists of several decomposition concepts, which are elemental intentions, partial intentions, and a universal intention. And also, each concept is defined as inclusion/affiliation relationship with other concepts. For the representation of elemental intention, we implemented an musical interface, Color note, which represents the colors and notes according to response of participants. We also propose Harmonic Defragmentation (HD), which arranges the partial intentions with harmonic rule. Finally, the universal intention is inferred to the comprehensive direction of elemental intentions. We used Karhunen-Lo$\`{e}$ve(K-L) Transform for the inference. For verifying the validity of our proposed interface, the "Color Note," and the various techniques, we installed our work and surveyed various users for the evaluation of HD and statistical techniques. Also, we commissioned another survey to find out satisfaction measurement which was used for expressing universal intention.

산업 전반에 걸친 활발한 디지털로의 진전은 영상산업의 전통적인 방법을 변화시키며 새로운 형태로 발전하고 있다. 이러한 영상산업의 발전 중에서도 모션그래픽(Motion graphic)의 활용도와 중요성은 비약적으로 발전하고 있다. 컴퓨터 그래픽은 그 짧은 기간의 역사에도 불구하고 다른 예술분야의 특성을 차용하여 예술의 한 장르로 빠르게 진화하고 있다. 특히 빠른 시간 발전하는 국내의 미디어 환경 속에서 모션그래픽은 전통적인 디자인 영역과 새로운 영역의 디자인에서도 모두 관심을 모으는 부분일 것이다. 짧은 시간 동안 모션그래픽은 영화, 광고, 뮤직비디오, TV, web 등의 모든 분야에서 활용되는 매체로 성장하였다. 그러나 이러한 장르로서의 모션그래픽이 등장한 시점은 얼마 되지 않았으며, 디자이너들이 이러한 영상에 자유로운 기법이나 실험성을 가지게 된 것도 극히 최근의 일이다. 이에 본 논문의 목적은 이러한 발전하는 디지털기반의 영상 제작 환경에서 영상의 한 요소로써의 모션 그래픽의 기본적 요소를 고찰함으로, 이 개념을 정립하려고 한다. 그 요소로는 공간, 모션 그래픽의 객체들의 시간개념과 움직임, 색체와 사운드를 규정하고, 이를 여러 디지털적인 환경에서 규정한다.

Due to the rapid development of information & communication technology under high performance computing environments, the multimedia production techniques have been applied to a variety of multimedia fields such as general banner advertisements including texts, images and animations, and the internet-broadcasting dealing with videos and sounds. This paper presents an authoring tool with main functions to setup events objects (image, animation, sound, button, area) and to setup action functions, so that non-experts can easily produce multimedia including images, sounds, animations and so on. The authoring tool implemented in Java can be applied to the CD-ROM title production as well as the web-site construction. We can expect that when this authoring tool is used for in multimedia production, both cost and time will be reduced due to its convenience and powerful functions. We have a future plan to integrate intelligent multimedia presentation techniques with the presented tool for the autonomous multimedia authoring works.

This study is subjected to two linked research. First is the creation process of dance work applying noise and non-musical sounds in our daily life based on understanding the classification, perception, and factor of the sound, through Murray Schafer's concept of 'soundscape'. Second is to find the value of new type of choreography and musical effect of creation process of the dance work . According to methodological research of practice-based research, three stages which is practice, theory and evaluation were accumulated as somatic data, And the analysis was provided a basis by presenting in a figuration, form of the movement and method of specialization with reference to the paper 『space design and forming practice』(2003). As a result, the creation process was able to discover the musical effect of the sound in daily life and new method of choreography, and also find the possibilities that sound could convey the theme of the dance work, the meaning of the movement and the overall atmosphere of the work to audience. In addition, It is expected that will have been made another new creation environment by potential that music has based on concept 'soundscape'.

This paper will study the influence of comedic elements of the game on the gaming choice by the game users, and focus its goal on establishing the foundation for the various game production environments. Within the game, the comedic elements are categorized as one of actively expressive elements and enhance the game's entertainment together with its sound qualities of graphics, scenario, sounds and level designs. Although the comedic elements are generally acknowledged as necessities, the research on how the users actually perceive those elements has been insufficient. Therefore this paper will investigate characteristics, compositions and techniques of the comedy used in the game and will analyze the influence that those comedic elements have on the users' recognition, satisfaction and royalty to the game.

Multimedia element of the game graphics and sound, etc. 'commitment' that plays an important role in gameplay. Therefore, the quality of the game is closely related to the quality of multimedia elements that can be. In this study, various competitions in the field of content screening criteria based on previous studies and multimedia elements of the game area, and domain-specific details about the quality of sub-elements were extracted. Assessment areas and sub-elements extracted to verify the need for the game will be carried out surveys among the users. The findings in the next game production shall be deemed to be an important reference material.

Games in 1970s have used the savings of analog wavelength as in music and the like on hardwares of small cassette, gramophone, and the like. Due to these configuration elements, durability has to be declined so much. In the event of using the music on the video game, more affordable method is to use the computer chip to convert the analog sound into the computer code to convert into the electric wavelength to send to the speaker. The sound effect of the game is generated in this method. The technical limit has been gradually overcome to grant more freedom to the composers and the sound track pre-recorded on the optic disc and the like has emerged. The game developers of today have made several attempts on the technology to produce the game music. This study has contemplated the process of advancement in the change of game music production with the influence on technology and business.
